[Gambas-user] Sample code to convert image to b/w image

[Safiur Rahman]

Hi

I want to achieve the following black-in-white image output with
Imagemagick with gambas
$ convert old.png -alpha off -threshold 50% new.png

Any sample code to achieve it?

Also using Image.Opacity and Image.Threshold, I get following errors

With Image.Opacity(50) I am getting error "The image must have an alpha
channel"
With Image.Threshold(0.5) the gambas crashed.
